Randomized Controlled TrialEffect of mini-dose epidural dexmedetomidine in elective cesarean section using combined spinal-epidural anesthesia: a randomized double-blinded controlled study.
Combined spinal-epidural anesthesia is commonly used for elective cesarean section. Our study aimed to evaluate the effect of adding dexmedetomidine to epidural bupivacaine and fentanyl in patients undergoing elective cesarean section using combined spinal-epidural anesthesia. ⋯ The addition of mini-dose epidural dexmedetomidine 0.5 µg/kg as a single injection to bupivacaine fentanyl in women undergoing elective cesarean section with combined spinal-epidural anesthesia improved intraoperative conditions and the quality of postoperative analgesia.

Randomized Controlled TrialLaryngoscopy facilitates successful i-gel insertion by novice doctors: a prospective randomized controlled trial.
This study investigated the hypothesis that the efficacy of insertion of the supraglottic device i-gel(®) (i-gel) can be improved by laryngoscopy and can provide better sealing pressure in anesthetized patients by novice doctors. ⋯ Our results suggest that laryngoscopy facilitates i-gel insertion by novice doctors, as reflected in the rate of successful insertions, higher sealing pressure, and lower subjective difficulty of insertion in anesthetized patients.

The uses of laryngeal mask airway ProSeal™ and endobronchial blocker for one lung anesthesia.
The use of an endobronchial blocker in conjunction with a supraglottic device in elective thoracic cases has never been studied. The aim of this study was to report the success rate and time to placement of the endobronchial blocker in anaesthetized patients with a laryngeal mask airway (LMA)-ProSeal™ in place. ⋯ The use of LMA-ProSeal™ in conjunction with the COOPDECH Endobronchial Blocker Tube may be considered an alternative one-lung ventilation technique in selected cases. However, success rates and time required for placement of the blocker seem dependent on the operator's skill. Although postoperative sore throat and hoarseness of voice were reported, these improved in 24 h.

The efficacy and safety of combined pulsed and conventional radiofrequency treatment of refractory cases of idiopathic trigeminal neuralgia: a retrospective study.
We conducted a retrospective study to evaluate the efficacy and duration of pain relief for idiopathic trigeminal neuralgia (TN) patients after continuous radiofrequency (CRF) combined with pulsed radiofrequency (PRF) treatment of the Gasserian ganglion (GG). ⋯ Excellent pain relief and reduced consumption of analgesics for more than 6 months were observed in patients who received PRF combined with CRF to the GG for treatment of idiopathic TN.

ReviewHistory of T-cain: a local anesthetic developed and manufactured in Japan.
In many anesthesia textbooks written in English, lidocaine, tetracaine, bupivacaine, ropivacaine, and chloroprocaine are listed as useful local anesthetics for spinal anesthesia. In contrast, T-cain is not included in these lists, even though it has been reported to be suitable for spinal anesthesia in Japan. T-cain was developed as a local anesthetic in the early 1940s by Teikoku Kagaku Sangyo Inc. in Itami, Japan, by replacing a methyl group on tetracaine (Pantocaine(®)) with an ethyl group. ⋯ Other than the side effects generally known for all local anesthetics, serious side effects have not been reported for T-cain. In fact, several articles have reported that T-cain decreases the neurotoxicity of dibucaine. In this historical review, the characteristics of T-cain and its rise to become a major spinal anesthetic in Japan are discussed.
